To all whom it may concem:

Be it known that I, SEWARD Homes CALKINS, a citizen of the United States, and

a resident of the city of New York, Long ti Island Cit borough .of Queens, in the county of ueens and State of New York, have invented a new and useful Pattern and Guide Strip, of which the following is a full, clear, and exact description.

This invention relates to pattern and guide strips for plastic work, and has for an object to provide an im roved device which will permit the ready epositing and finishin of wall or floor coatings of a number of di erent colors without the various colors comminglin Another 0 jectof the invention vide a strip which acts as means for ing the plastic material when being in position and also as a leveling and controlli means.

A still rtherf object in view is to provide a stri which will act as a guide and pattern a for p astic floors, walls, and the like, which is to prouidp aced eight vill! will in addition provide forthe expansion of material and which :need not be removed after the work has been completed, so that i the same or difierent colors may be readily used and treated in the proper manner for so producing the best results.

' In the accompanying drawings:

Figure 1 is a longitudinal vertical section through part of a floor showing a pattern and guide strip embodying the invention. as Fig. 2 is a top plan view of the guide strip shown in Fig. y

3 is a fra mentary perspective view showmg an embo iment of the invention applied to a wood floor. v Fig. 4 is a fragmentary top plan view of a finished piece of floor construction with a pattern and guide strip embodying tho iuvention.- 7 Fig 5 is a detail fragmentary f i a view showing two guide connected to gether end to en 3 of a slightly modiof guide strip.

erspective 6 is an end view In laying concrete floors, walls, 'or ceilings, the material must be properly m xed F' 7 is a view. of a art of a, so strip 0 the kind shown inlig 6.

and placed in position andthen allowed to season or harden before it is used, Where a mosaic is to be provided, for instance what is known as a terrazzo mosaic the concrete is mixed with coloring matter if desired. and also with marble or other material, and is pressed by any suitable means, as for instance a roller until the texture is comparatively close. After this has been done the prepared floor is allowed to season or harden to a certain extent, which requires several days. After it has been propprly seasoned or hardened by the action of t e air, the top surface is ground, either manually or by a inding machine to reduce a smooth evennish. Ifthe grinding action takes place before the floor has properly set the floor will be so soft as to cause an undesirable grindin away and a less desirable finish. If the oor is allowed to set too long and becomes too hard the grindin is more difficult and the'finish' 0r polish shot so satisfactory. For this reason workmen are careful to grind the floor at the proper time.

Referring to the accompanying drawings by numerals, 1 indicates a foundation of any kind on which a lower bed 2 is placed, said lower bed being cement, sand, and if desiredgravel, mixed toprovide a comparatively compact bed. This lower bed is then levelledofl by any suitable means. While this bed is still green,or soft, a stri 3 is placed in position thereon and force downwardly until the wings 4 en age the upper surface of the lower bed 2. y means of the win s 4 the strips are held in such a osition t at the upper edge of the strip 3 will be at a certain height from the-upper surface of the lower bed 2. Preferably e lower bed 2 is madeof the proper thickness to allow the edge of, strip 3 to rest on the foundation 1, thou this isnot essential. The' arrangement of t e parts asjust described permits the strip 3 to act as a hei ht guide when placing the upper bed or fini in layer 5- in lace.

Informing t e strip 3, t e win. 4 are pressed out from the lower half of t e stripalong a predetermined longitudinal line, preferably the central longitudinal line, to and including portions of the lower of thestrip.

Prefers 17 also, the wings 4 are pressed out from the body of the strip on vertically tically inclined mar cording to the length or Inclined lines converging toward the lower edge of the strip as shown inFig. 1. By means of such construction, the opening formed by pressing out said wings has verins, and when the stri is placed inthe un er bed while the bed is in a semi-plastic condition, the material forming the bed is ressed into said opening and forms, wit the bed, a keystone sha dinterlocking connection between ,the un or bed and strip, stri against vertical displacement.

' vahile not essential in all cases, it isdesirable to slit the portion pressed out from the lower half of the strip so as to form double wings arranged in juxtaposition on 0P$l slte sides of the strip, as shown in Fig: 2. y such means, the stresses imposed-upon the strip by the upper bed or finishing coating are evenly distributed, and contribute materially =towar holding the strip in fixed position, and toward maintaining an even expansion .of the upper bed alon the line the strip, and prevent irregu ar crackg of said bed or surface.

11 addition'to the wings levelling members 6 may, if desired, be pressed out from thelower half of the strip, and twisted so as to place the faces thereof at shown.

After the strip has been'placed in position and the lower member (Swill also act as a firm anchor for holding the strip against displacement.

e strips 3 are notched at" intervals, acdesign desired and transverse s'trips 3' and 3" and are-interlockedin Fig. 2. The strips 3 and have any desired number of wings 4 and anchoring membersfi, so that it will remain in proper position regardless of its the way in which it is bent or with strip 3 as vshown maybe of any length formed.

ing a ring 7 made from a strip 3, in which a quantity of a certain colored material 8 is deposited, the material exteriorly of the ring being of a. different color. The flooring shown in Fig. 4 is arranged with-al number of different Other forms could be provided without departing from the. spirit of the invention. When forming the floor shown in Fig. 4 or wall, or ceilnig, strips 3 areproperly shaped and placed in position as shown in Fig. 1 and described in connection with said fi ure. The various colored plastic materials are thensupplied to the various places desired, said depositing of the various materials bein Y done at one time so that the aging will be even throughout. After the that securely holds the not necessary. Wh 4, anchoring andan angle to the sides ofthe. strip, as

bed 2 is allowed to harden,

are similarly notched- In Fig. 4 a finished floor is shown havi cleavage.

material has been properly aged a grinding machine is passed over the floor and the floor ground .to the desired extent.

be strips 3 other material could be used, brass being desirable because'it will grind away easily along with the upper surface of or other material used in the body of the floor. Ordinarily the strips are arranged as shown in Fig. 1, and if it is desired to place a mosaic on a Wood floor the strips maybe held against saidfioor by nails 9, Fig. 3), said nails passing through suitable apertures in the wings 4. v

In some circumstances it might be desirable to provide astrip 10 similar to strip 3, except that it is solid throughout. In'order to properly also to properly support the same on the lower bed 2 a' c'lip 11 is provided havin -a U-shaped section said 'Ushaped section merglng into side wings 12 and 13. If desired the clip 11 could be soldered, riveted, or. otherwise secured to strip 1 0, though ordinarily this is ere two strips 3, or two strips 10 are to be arran overlapping joint is provided-as shown in Fig. 5. This structure isprovided by merelyslitting one of the strips 3 at 14 and bending the sections 15 and 16 to one side so that the end of the next adjacent strip 3 may he slid therein.

From the foregoing" ered in connection with drawings, the construction, manner of use, and the several advan s of the present invention will be clearly and fully understood.

All ,concrete floors, walls, and ceilings are subjected to the strains and stresses caused are preferably brass, thoughinto which the strip'lO ts,

the cement ged in tandem an tort-ion of their supporting structure, resulting at times, in cracks forming in the floors,

walls and ceilings. At first dividing st-ri s purpose ofdividing the flooring into sections-so that if cracks appeared in the flooring, the section containing the cracks might be cut out and relaid without chsturbingthe adjacent sections. Inciden .tally such an arrangement provided means for filling the terial of. different coloring.

But a' dividing strip in and of itself doesnot cont-rol the course taken by a crack or On the contrary, the dividing strip is subjected to the same forces that produce'the cracks, and omes loosened from its setting in the cement compound, and in'some cases its upper edge becomes exposed above the surface of the flooring, 111 'ng an unsightly and tionable surface.

In order to control, oraid in controlling respective sections with 'ma in the material forming t e otherwise objecthefeourse of a .bed, the strip bers 6. These members by being floor supporting this invention enables the flooring to be laid must'be enabled to maintain a fixedpositlon against stresses tending to raise the strip vertically and that is accomplished in the present invention by means of the anchoring wings4, and meme ressed out from the lower half of the strip through the lower edge thereof, enable the material forming the floor to be pressed into the openings formed by ressing out such p'or-' trons, which materia forms a component partof theunderbedj 2,"and together with the offset wings 4, hold the strip a ainst vertical displacement. When so'hel "the strip forms a path of least resistance in the flooring, and absorbs the cracl alon the line of the strip where it becomes practically unnoticeable. v y

In addition to taking care of cracks forming in the flooring due to distortion of the members, the device of in a facile, economical and practical manner with a minimum amount of eflort and in the shortest time possible, and in a manthat insures uniformity of setting or hardening of the material, thereby preventing any cracks to expansion or contraction of the flooring V itself.
